Moises Sierra

The Blue Jays announced, via press release, that they’ve designated outfielder Moises Sierra for assignment in order to clear a 40-man and 25-man roster spot for infielder Steven Tolleson. Toronto also announced that Jonathan Diaz has been optioned to Triple-A Buffalo, with outfielder Anthony Gose being recalled to take his place.

The 25-year-old Sierra struggled greatly in his time with the Jays this season, collecting just two hits and a walk against nine strikeouts in 35 plate appearances. Despite his lack of production in 2013, however, Sierra was a well-above-average bat in 2013, slashing .290/.369/.458 in 122 plate appearances at the Major League level. Sierra has posted an identical .782 OPS in his career at the Double-A and Triple-A levels.

Tolleson, 30, has a bit of Major League experience with the A’s and Orioles, having batted .225/.273/.350 with three homers in 129 plate appearances. He’s been highly versatile throughout his career, playing second base, shortstop, third base and all three outfield positions. At the Triple-A level, Tolleson is a .285/.368/.409 hitter in 2040 plate appearances.
